This is an application that tests your ability to guess. You will have 8 blue circles and from 1 to 7 green circles hidden underneath the blue circles you will have to find. You can find them by clicking the blue circles. When you click on a blue circle, if there is a green circle behind, the blue circle will change its color into green, otherwise it will change in red. Every time you find all the green circles in a session, a new session will start. There are 10 sessions for each level and each level has a different number of green circles you have to find. The game counts how many times you failed trying to guess where the green circles are. The best score will always be equal to 0 failures. Enjoy and see what you score will be.
